laravel failed to send email

When using the Laravel framework to send emails, if the sending fails, it may be due to the following reasons:

1. The email account or password is incorrect

If You are using the SMTP service provided by your email service provider, so please check whether your email account and password are correct, otherwise the authentication will not pass and the email will fail to be sent. In addition, some email service providers may require you to turn on the "Third-Party Authorization Code" to gain access to your SMTP email, so please check these necessary information.

2. There is a problem with the sender setting

When using Laravel to send an email, you need to set the sender's email address and name, otherwise it may be rejected by the email service provider may be mistaken for SPAM emails and filtered. Please confirm that your sender settings are correct and that the identities allowed by the mail server to send emails are consistent with the identities you set.

3. Mail server failure

If your email service provider fails or is undergoing maintenance, it may cause failure to send emails. Please check whether the mail server status is normal, and confirm whether the port number, SSL encryption and other settings you are using are correct. It is recommended that you first check whether the web version of the mailbox can be logged in normally in the browser, or use other email clients to test to confirm whether the problem occurs in the Laravel framework.

4. Spam filtering

Some email service providers may have a spam filtering mechanism that automatically filters or moves emails suspected of being spam to the trash. If your email resembles SPAM, it may be filtered and not be sent successfully. Please make sure that the content of your email is legal, does not contain sensitive words, does not contain excessive advertising content, etc. You can also try to adjust the title, content, pictures and other elements of the email to avoid being misjudged as spam.

5. Laravel email configuration error

If the above reasons have been checked and you still cannot send emails, it may be because the email configuration file in Laravel (config/mail .php) is incorrectly set. You can check whether your email driver, email server address, port number, encryption method, sender information, etc. are set correctly, and whether they are consistent with the information provided by the email service provider.

Summary:

Through the above investigation, I believe you can now find the reason why the email fails to be sent. When using Laravel to send emails, you need to pay attention to the above details, eliminate the possibility of problems as much as possible, and ensure that emails can be sent successfully.
